Definitions

  • the invention relates to polyacetylene made conductive by incorporation of dopant, and in particular in the form of flexible and mechanically resistant film (film).
  • the invention encompasses the manufacturing and doping process.
  • the European patent application published under No. 0 026 234 on October 16, 1980 gives a process for manufacturing a material whose structure, having microcrystalline fibers, lends itself well to the manufacture of such films.
  • This material comprises polyacetylene with a high degree of polymerization and at least one electron accepting dopant such as nitric or sulfuric acid or a mixture of strong acids, or the oxide S 0 3 , a chloride or a boron bromide. , or finally a naphthoquinone optionally substituted using hydrogen, or halogen or a cyano, nitro, alkyl or alkoxy radical.
  • a conductivity material can thus be obtained which can vary from 10 -9 ohm .cm to 10 ohm .cm, which, in the form of a film, has acceptable characteristics of flexibility, mechanical strength.
  • the conductivity thus obtained is not uniform in the thickness of the material and, moreover, rapidly disappears over time.
  • the invention tends to eliminate these drawbacks by replacing conventional dopants with dopants based on heavy elements which have low diffusion coefficients.
  • the material according to the invention is composed of polyacetylene and of a dopant constituted by a salt of an element belonging either to the family of transition metals or to the family of lanthanides.
  • the transition metals are chromium, nickel, iron, titanium, tungsten and molybdenum used in the form of chloride, and the lanthanides are europium and ytterbium.
  • FIG. 1 represents the doping rate as a function of the time of doping proper in two embodiments of the invention
  • FIG. 2 represents the conductivities obtained as a function of the amount of dopant in the same embodiments
  • FIG. 3 gives comparative characteristics of stability over time, in the case of the invention and in that of a conventional dopant.
  • Curves 1 and 2 represent the variations in this rate, respectively in the case of the dopant W C1 6 and the dopant Mo Cl 5 . We see that several days (10 5 to 10 6 seconds) are necessary to bring the dopant level above 0.05.
  • the decrease is small and the stabilization takes place at a rate of the order of 0.8.
  • the material according to the invention can be used, depending on its conductivity, either as an organic conductor or as a p-type semiconductor, either alone or in combination with an n-type semiconductor. It is applicable to the production of photodiodes and solar cells.
